Abstract

Cutting maize stalks using water jet cutting technology is a new method of stalk management before no-tillage sowing. Aiming to cut off the maize stalks (stems and stem nodes), we conducted an all-factor cutting experiment on stems and single-factor cutting experiments on stem nodes under different cutting parameters. The results showed that the cutoff ratio of the stems and stem nodes increased with water jet pressure and decreased with target distance and traverse speed. For cutting off the stems with a maximum traverse speed, the parameters were 120 MPa water jet pressure, 10 mm target distance, and 1371 mm/min traverse speed. When the target distance was 30 mm, the traverse speed was 4000 mm/min, and the water jet pressure was greater than or equal to 160 MPa, the cutoff ratio of stem nodes was 100%. Therefore, the water jet pressure ≥ 160 MPa, the target distance ≤ 10 mm, and the traverse speed ≤ 1371 mm/min were needed to cut off both. Moreover, bottom burrs, surface stripes, and cutting residue might appear due to the divergent and lagging characteristics of water jets. The results could provide basic data and technical support for cutting maize stalks with water jets.
